Well, the other side have perceived negatively and with frustration him raising the issues and asking the establishment inconvenient questions. Is there anything wrong with that?
No. HE complained that google only showed negative stories about him as he was claiming media bias. Google did a study and found that their algos picked up stuff he said and others reacted to. There wasn't a bias. Google found that it showed more negative articles about Hillary than positive.
so by the transitive property, trump called his own comments negative.
